They're both nicely designed guns, well except the barrel on the 2nd one could really do with an inside diameter so it's more like a barrel and less like a piece of cheap aluminium tube.
The thing that puzzles me is why?
They're both too high poly for a game, so I'm not sure why your making them - they're not even practice because low poly gun modelling is completely different to 'untapped' poly modelling.
Perhaps next you should make a little pack of low poly guns for free download, one stipulation you could add is that if they use the gun they must retexture it and send you a copy of the texture for your own use - kinda like a shared licence where both parties benefit from eachother but with no money changing hands.
